Cost-Sentry: Optimizing AWS Spend with AI-Driven FinOps Auditing

What I Built In a sprawling cloud environment, "zombie" resources specifically unattached EBS volumes are a silent drain on the budget. As a Cloud Architect, I wanted to build a tool that doesn't just manage infrastructure but optimizes its cost. I built Cost-Sentry, a FinOps agent that identifies unattached EBS volumes and calculates their financial impact. It uses the GitHub Copilot CLI as a reasoning engine to generate complex Boto3 auditing scripts, which are then used to produce immediate, actionable saving reports. Demo The tool is designed for high-velocity cost audits and is now part of my public GitHub portfolio. 🔗 GitHub Repository: https://github.com/mpawar006/cost-sentry Cost-Sentry in Action The tool scans for volumes in the available state and applies a standard rate of $0.10 per GB/month to estimate waste. Figure 1: Cost-Sentry successfully identifying 20GB of unattached storage waste. Financial Impact Detected: Total Volumes Audited: 2 Total Wasted Capacity: 20 GB Poten
